A few more data points on this. I consistently get this oops on our new Dell 
PowerEdge M600, but do not get the oops on a Dell PowerEdge 1955. They are the 
same model card, but slightly different revisions:
Dell M600: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 
08)
Dell 1955: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01)

I applied the upstream patch to the 2.6.24-12 sources and re-compiled
the module. The patch location was slightly different, but it patched
and compiled cleanly. I then swapped in this patched module after the
"Loading Additional Components" step, but before the "Configuring the
Clock." With the patched module, the installer is able to load the
module and the installation proceeds normally. Of course, the unpatched
module gets installed in /target, so I have to swap it in there before
the reboot so that the machine does not panic at boot. :-)

I'm not sure what the next steps are to help the kernel team get this
patched, but I'm happy to provide any additional information and/or
assistance. If this could make it into hardy final, we'd love to see
this, since we're trying to move our servers to the LTS release.

I've attached the actual patch I used on the hardy linux 2.6.24-12
sources this morning.
